ok guys it has been brought to my attention by good sources that the Bk-9 for the most part will have the bk-5 sound set with a few super natural sounds as I hear the Demos being a BK-5 owner I can hear it and it not just a bad player the sax sounds is bad horn sounds are not good maybe the tone wheel stuff will be good for organ sounds pianos are nice on BK-5 as for pad and strings very nice as well but it is what it is it will not have the thickness we want that is upsetting to me Roland has the abilty to put much better sounds in those areas the integra and G series synths have much better sounds pianos and el pianos, organs, strings good but the other stuff not good my Tyros 4 will fill in where the Bk-5 -9 falls short SAX sounds for sure I was hopeful Roland would of put a much full sound set in like there top of the line sound set and not the past BK sound set bad move for them . sadly this will make it a MOTL unit 76 keys will make me want one but for the price they are asking better sound set should of been added so the demos are what you hear BK- 5 type of sounds because that is what it is
